Brison: England began their Champions Trophy preparations with an emphatic seven-wicket one-day win in their first home international match against Ireland.
The tourists fell apart after a good start, losing their last eight wickets for 45 as Adil Rashid's first ODI five-for helped dismiss them for 126.
England's reply began badly as Jason Roy was caught without scoring.
But a typically brutal 55 from Alex Hales and unbeaten 49 from Joe Root saw England home with 30 overs left.
Most of the praise for Eoin Morgan's side has focused on their brutal scoring with the bat, but it was their ruthlessness with the ball that brought them victory on Friday.
On a benign track at a cold and windy Bristol it initially appeared to have been a good toss for Ireland to win, as the aggressive Paul Stirling and efficient Ed Joyce added a quick-fire 40 for the opening wicket.
But England, without IPL quartet Ben Stokes, Chris Woakes, Jos Buttler and Chris Jordan, halted their progress with the dismissal of both openers in quick succession - Mark Wood bowling Stirling before David Willey trapped Joyce lbw.
From that platform, the home side spun the game decisively in their favour, with Rashid the star turn thanks to his 5-27.
That was his first five-for in ODIs and the second best figures by an English spinner in the format, behind only the 5-20 taken by Vic Marks against New Zealand in Wellington in 1984.
Combining superbly with fellow Yorkshire player and spinner Root, Rashid demonstrated control and variation to bamboozle Ireland, who lost their last eight wickets for just 45 runs.
The second and final ODI of this series is at Lord's on Sunday.
Ireland - 126 (Rashid 5-27, Root 2-9)
England - 127 for (Hales 55, Root 49*, Chase 3-44)
Result - England won by seven wickets
